Types of data extraction: what you need to know

 





Data extraction is the act of extracting data from a source and transforming it into another form for use in another application. In other words, data extraction helps you get data from a source and make that data readable for your own software or database. Data extraction can be manual or automated and depends on various factors, e.g. B. from the data source, the attributes and properties of the data and the frequency of access. If you are in an industry that requires frequent access to large amounts of data, such as For example, in healthcare or manufacturing, you will likely find many uses for data extraction processes. Incorporating some form of data extraction into your business practices gives you more time and energy to focus on activities that will benefit your business in the long run.

 

How to perform data extraction?

Data extraction can be performed manually or automatically. With manual data extraction, the data is read from a source and then manually entered into another application. Manual data extraction is often used when the volume of data is small and/or the structure of the data is predictable. Automatic data extraction is software controlled and can be used when the volume of data is large and/or the structure of the data is unpredictable. Automatic data extraction often involves using a computer program to read data from a source and then transfer it to a desired destination. Automatic data extraction can be done manually or semi-automatically via an interface.

 

What is manual data extraction?

Manual data extraction is an offline method of extracting data from a source. Manual data extraction is used when the volume of data is small, the structure of the data is predictable, and the data needs to be extracted frequently. In manual data extraction, a person reads the source's data and then manually enters it into another application. Manual data extraction is often used for data that is not time-sensitive, such as B. the product catalog of a company. Manual data extraction is also used when the data source is not available online. When extracting data manually, you should verify the accuracy of the data by comparing the data to the source.

 

What is automatic data extraction?

Automatic data extraction is an online method of extracting data from a source. Automatic data extraction is used when the volume of data is large or the structure of the data is unpredictable. Automatic data extraction is often used for data that is time-sensitive and needs to be extracted regularly. In automatic data extraction, a computer program often reads the data from the source and transfers it to a desired destination. For example, if you work in healthcare and you need to find medical records from different hospitals across the country, you can perform a data extraction that takes the data from each hospital's electronic medical record (EMR) and writes it to a single database. Automatic data extraction often involves using a computer program to read data from a source and then transfer it to a desired destination. Automatic data extraction can be done manually or semi-automatically via an interface.

 

Types of automatic data extraction

- Extraction method - An extraction method is an algorithm that applies rules to a data set and creates a new data set that represents an extraction. - Extraction Model - An extraction model is a program or set of statements used to define a data source, source attributes, and the format of the extracted data. - Source Transformation - A source transformation is a process used by a computer program to read data from a source and create a new dataset. - Target Transformation - A target transformation is a process used by a computer program to read a record and write it to a target.

 

What are the benefits of data extraction?

- Improved Data Consistency - By using an automated data extraction tool, you can more easily monitor data consistency and track any data quality issues. This allows you to identify and correct any problems with the data before it's too late. - Fewer data entry errors - When you use an automated data extraction tool, the likelihood of data entry errors is greatly reduced. This is even more true when you use an automated data extraction tool with validation features that allow you to spot potential data issues before the data enters your system. - Greater Efficiency - When you use an automated data extraction tool, you can complete tasks faster and with a smaller team. That's because employees no longer have to manually enter data, which can be time-consuming and error-prone. - Improved Data Quality - Using an automatic data extraction tool, you can easily monitor data quality. This allows you to identify and correct any problems with the data before they become a problem.

 

Key Results

- You can perform data extraction manually or automatically. Manual data extraction is done offline while automatic data extraction is done online. - Data extraction can be used to transfer data from a source to a desired destination. It can also be used to transfer data from one source to another. - Data extraction is useful to improve data consistency, reduce data entry errors and improve data quality
